Sounds pretty good. I like the chill vibe. The first verse feels a little empty. In the future, you might want to add more than a pad, vocal, bass, and melody (trumpet). You did a good job with it here, but it might sound more complete if you added just one other instrument like a piano or guitar.
Good job with the drums. I like the kick. The shaker is a little to loud in my opinion. For the future, you might want to consider adding cymbals. Overall, you did a good job mixing what you had but you might want to add more in the future. Best of luck in the competition
